I got to say. Not only am I not interested in this challenge I'm surprised anyone is.
Because entitled much? You demand that someone write your long complicated plot, (incredible a-canonical and ooc plot that someone has to try and make it work for you) and then you demand it has to 50,000 words long. (Are you any kind of writer? Because that's a freakin novella)
And then you whine about how unreliable fanfic authors are how you must totally promise to finish it if you start. Because people don't have real lifes or anything. They can't start something in good faith and then not able to finish it.
so... yeah, No.
